LC Labs has been the primary worldwide supplier of PMA for laboratory research for more than 36 years

More than 250,000 vials of our PMA have been used by many thousands of labs since 1980

More than a dozen major biochemical reagent vendors sell our PMA under their own labels

Thus, any PMA you may have used during the past few decades was mostly likely manufactured by LC Labs

Our 1, 5, 10 and 25 mg sizes of PMA are now regularly supplied in crimp-top vials with teflon-lined septum seals for easy reconstitution and liquid handling. This new form of packaging replaces the flame-sealed snap-top vials that we used previously for those sizes.

The 100 mg size of PMA will continue to be supplied in flame-sealed snap-top vials under a nitrogen atmosphere for long-term stability (many years).

We continue to offer PMA in flame-sealed snap-top vials for all sizes. Please request "Flame-Sealed Vials" when placing your order.

This is the most commonly used phorbol ester. It binds to and activates protein kinase C, causes an extremely wide range of effects in cells and tissues, and is a very potent mouse skin tumor promoter. Blumberg, P.M.
